Hi Andy, we use jboss 4.3.2 / 5.0.1, and xymon client. For Runtime bean the problem was "not registred" values, until the first access from jmxconsole. I solved adding the command

curl 'http://myserver:myport/jmx-console/HtmlAdaptor?action=inspectMBean&name=java...' > /dev/null

in jmxstat.sh. Probabily i have the same problem for the column GCInfo, collect on the version 5.0.1 but not on 4.3.2

I use the shell script for xymon, and the environment seem to be correct. I get this error + PATH=/bin:/usr/bin:/sbin:/usr/sbin:/etc:/usr/lib/jvm/java-1.6.0-sun-1.6.0.26.x86_64/jre/bin

JMX seems to report memory in kb (jboss 4,2.3). So, if i consider the conversion in the tcl in mb, and on the graph in gb, i get correct values (es . max heap size). Found this link about (for 1.5.0) : http://docs.oracle.com/javase/1.5.0/docs/guide/management/jconsole.html#summ...

On the version 4.2.3 i need to add a new section for ThreadPool ( jboss.web:typeThreadPoll,name=http-myipserver-myports). Not always find the way to make graph :- (the value and the color status are "attached" )

Hi,

Thanks for the feedback, good to hear you like it.

Regarding your questions, Memory is reported by JMX in bytes and this is converted in the tcl code to kbytes to avoid overflows in the integer arithmetic.

There is no Uptime bean, it is an attribute of the Runtime bean, I called it 'fake' because I wanted to treat it specially. Are you saying something fails for some JVM? Have they been running for a very long time, maybe uptime is overflowing? Let me know the Java version and the JBoss version I'll have a look if I can replicate it here.

If you need to specify the JVM for xymon then it sounds like the script is still trying to run bbhostgrep instead of xymongrep, anything in the logs?. There is a different shell wrapper for hobbit and xymon in the latest kit, and you need 0.1.3 of the tcl script.
Have a look at the tcl script starting at line 5961 for how I envisaged this would work, the key is finding XYMONHOME in the environment instead of BBHOME. Let me know if you solve this please.

set XYMONCOMMS "xymon" set XYMONSEARCH "xymongrep"

inherit this from the environment or startup profile if its there

if { [info exists ::env(XYMONHOME) ] } { set XYMONHOME $::env(XYMONHOME) } elseif { [info exists ::env(BBHOME) ] } { set XYMONHOME $::env(BBHOME) set XYMONCOMMS "bb" set XYMONSEARCH "bbhostgrep" }
